Abstract

PURPOSE:To improve the value of a product by installing a burr reomoing tool for removing burrs generated in the cutting by a cutting tool. CONSTITUTION:A product Ws which is formed by cutting a work W by a band saw cutter 9 is clamped by the operation of a cylinder 25A between the fixed vice jaw 23A, of a front vice 21A and a shiftable vice jaw 27A. Then, an electric motor is driven to transport the product Ws to a burr removing position in the X-axis direction. At the burr removing position, a burr removing device 29 having a chamferring cutter 35 on a base 33 which is shiftable in the vertical direction on a rack board 31 in the Y-axis direction is arranged. The chamferring cutter 35 which is revolution-driven is raised by a cylinder 45 and allowed to act on the burr Wv generated in the lower part of the cut part of the product Ws, and burr removing is carried out.

[0002]

2. Description of the Related Art Conventionally, when a work is cut with a band saw, for example, as a cutting machine, burrs, burrs and the like are generated at the end of the work. The burrs and burrs particularly occur on the product side, and the material side is clamped by the body vice, so the burrs and burrs are relatively rare.

[0003]

By the way, burrs generated when a work is cut by the above-mentioned conventional cutting machine,
There is a problem that burrs not only reduce the value as a product but also become a rejected product as a material for forged products and where dimensional accuracy is required.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a deburring device for a cutting machine, which is intended to improve the product value by removing burrs, burrs and the like generated at the time of cutting a work in order to solve the above problems. .

[0005]

To achieve the above object, the present invention provides a cutting machine equipped with a vise device for clamping a work on a base, and the work is cut by a cutting tool of the cutting machine. A deburring tool for removing the burrs generated on the workpiece was sometimes provided to configure the deburring device of the cutting machine.

[0006]

By using the deburring device of the cutting machine of the present invention, when the work is cut by the cutting tool of the cutting machine,
Burrs generated on the work are removed by a deburring tool of the deburring device. Therefore, the product value can be improved.
